蜂蜡油品质影响因素探究

The Research on Influence Factors of the Quality of Wax Oil

目的:研究不同加热时间和贮存时间蜂蜡油过氧化值和酸值的变化趋势,为蜂蜡油的炼制及贮存提供科学依据。方法:根据《中国药典》第四部通则中“脂肪与脂肪油测定法”中关于过氧化值和酸值的检验方法,对不同加热时间和贮存时间的蜂蜡油进行测定。结果:(1)加热时间在60 min以内时,蜂蜡油中的过氧化值增幅缓慢,随着加热时间继续延长,蜂蜡油中的过氧化值迅速增加,至90 min时蜂蜡油中的过氧化值增加了6倍,酸值增高近80倍;(2)贮存时间在15 d内时,蜂蜡油中过氧化值和酸值增加缓慢,而超过15 d后,蜂蜡油中的过氧化值和酸值急剧增加,酸败反应加剧。结论:加热时间控制在60 min以内时对蜂蜡油品质的影响较小;贮存时间在15 d内时,蜂蜡油的酸败反应缓慢,减少贮存时间可延缓蜂蜡油的变质。该研究对蜂蜡油的合理炼制及贮存具有一定的指导意义。

Objective:Scientific basis for refining and storage of beeswax oil could be provided,with the research of the variation trend of peroxide value and acid value in beeswax oil under different heating time and storage time.Methods:The beeswax oil with different heating time and storage time were measured,according to the test methods of peroxide value and acid value in the mensuration of fat and fat oil in the four general rules of Chinese pharmacopoeia.Results:Within 60 minutes of heating,the peroxidation value of beeswax oil increased slowly.With the extension of the heating time,the peroxidation value of beeswax oil increased rapidly.When the heating time was 90 minutes,the peroxidation value of beeswax oil increased by 6 times,and the acid value increased by nearly 80 times.When the storage time is less than 15 days,the peroxide value and acid value in the beeswax oil increased slowly.But the peroxide value and acid value in the beeswax oil increased sharply,and the rancidity reaction intensified after 15 days.Conclusion:Within 60 minutes,the heating time has less effect on the quality of beeswax oil.When the storage time is less than 15 days,the rancidity of beeswax oil is slow,and reducing the storage time can delay the deterioration of beeswax oil.The research has a guiding significance for the reasonable refining and storage of beeswax oil.
